Java ee timestamp json serialisation format

Question

Is there a way to define timestamp serialisation in restful webservices, so I can exclude time zone?

@GET
@Path("{id}")
@Produces(MediaType.APPLICATION_JSON)
public Dto getById(@PathParam("id") Id id) { /**...**/ }

This produces json carrying timestamps formatted like this: 2014-12-14T16:29:52.416371+02:00

and I need only: 2014-12-14T16:29:52.416371

EDIT ISO 8601 format would do fine instead

If you use Jackson for your JSON serializer there are several ways of doing custom serialization. You can read more here.

One of the ways of doing it is to use @JsonSerialize annotation with a class that extends JsonSerializer<T>

I know jackson, but in this case serialisation will have to be done by hand, iside my method? Or I can plug jackson into javaee framework? – Rimantas Jacikevicius Dec 17 '14 at 13:01
Yes you can configure your Jax-RS implementation to use Jackson for serialization. Just search for Jackson and Resteasy or Jackson and Jersey (or what ever you're using) and I'm sure you'll find instructions. – Simon Dec 17 '14 at 13:24
Where should I look? I have no clue – Rimantas Jacikevicius Dec 17 '14 at 13:28

You can do this in a serializer and JAX-RS implementation independent way if you implement a custom entity provider / MessageBodyWriter. See: the JAX-RS user's guide section on this topic
